Flow diagram depicting study selection and inclusion process. Briefly, the search strategy of online databases initially identified 393 related records on PubMed, Google Scholar, Cochrane Library, and Science Direct. However, after removing duplicates and irrelevant studies, only ten clinical studies were deemed suitable and included in this systematic review. All incorporated studies reported on the modulation of endothelial function and relevant cardiovascular disease-related parameters in PLWH on HAART.
